[Sports and inflammatory rheumatism].

The author analyses the impact of sport and it's relation with inflammatory rheumatisms. The mechanisms introducing a muscle atrophy of the patients with inflammatory arthritis permits a good understanding of these relations. The role of the effusion in the articulation, the biochemical disturbances of the synovial fluid, a raised temperature, and finally intrinsic muscle biochemical disturbances are analysed. These different measures are in relation with the beginning and maintenance of muscle atrophy. The practice of sport, especially based on endurance, of patients suffering from inflammatory rheumatisms maintains the muscle bulk and force.
